Vibration on ZT1742
It sounds like you tested a unit that has a bad pto belt. I understand there is another belt available that reduces the vibration. The dealer should have a bulletin on this and should have the belt replaced under warranty. The 1742 is a very good unit and does give a very good quality of cut.
Are you planning to use this unit for commercial purposes?
Just as an FYI, It is designed for homeowner use where the average yearly hours is less than 75.
I hope I have answered your questions.
